US Patent:

7394312, Jul 1, 2008

Filed:

Nov 14, 2005

Appl. No.:

11/164201

Inventors:

Michael A. Schoenberger - Cincinnati OH, US

Assignee:

Pioneer Corporation - Meguro-ku

International Classification:

H03F 1/14
H03F 1/52

US Classification:

330 51, 330207 P

Abstract:

The present invention is directed to an amplifier, which is able to re-configure its internal protection circuits based on an output signal level. This allows the amplifier to apply the best protection level to the present operational condition. The protection level or threshold for protecting the amplifier is dynamically adjusted to a lower threshold level, thereby making it more sensitive in certain operating scenarios. In one embodiment of the present invention, a first current protection threshold is used to operate an amplifier in a first state. If an event occurs, the amplifier protection circuit is re-configured and the amplifier continues to operate with a second protection threshold in a second state.

International Classification:

Abstract:

The present invention allows multi-amplifier systems to be implemented, while avoiding the difficulties associated with current multi-amplifier systems. One amplifier is a “master”, which controls the settings a plurality of other amplifiers (the slaves). If an adjustment needs to be made, only the master needs to be adjusted. The amplifier of the present invention is configured to operate in a plurality of modes. In one configuration, the amplifier is set to be in a “master mode”. In another configuration, the amplifier is set to be in a “slave mode”. In yet another configuration, the amplifier is set to be in a “slave-inverse mode”.
